Abstract: Objective: To evaluate the clinical effects of autologous tooth as bone graft material in maxillary sinus lateral lift. Methods: The wisdom teeth removed from one male patient were used to produce the dentin granules and mixed with autologous PRF. The materials were put into the left maxillary sinus after elevating the membrane follow the bone grafting. The patient was followed-up for 1 year to observe the bone regeneration effects and clinical outcome. Results: The postoperative reactions were mild. X-ray investigation demonstrated the new bone formation at the bone grafting site. The dentine granules were gradually absorbed. The implant placed at the grafting site was stable and patient was satisfied with the restoration function. Conclusion: Autologous tooth as bone grafting material is a feasible way to reconstruct bone defects around implant region. It is an effective technique.
